Boas digest a lot slower than ball pythons. They eat a lot less often, and do not follow the typical 10-15% body weight rule most use for ball pythons.

Give your boa a rat that does NOT leave a noticeable lump every 7-14 days.

A lot of people tend to over feed their boas. Boas should not be chunky like ball pythons, but lean and squarish in body shape.
